Infrared laser diode with visible illuminator for biomedical stimulation

摘要

The special laser diode device (LDD) leasing in the near infrared region (IR) with two wavelengths: $lambda$-1$/ $EQ 850 nm and $lambda$-2$/ $EQ 1000 nm, designed for laser therapy, is presented. This device is characterized by a unique feature, namely a separate built-in illuminator, operating in 670 nm. The special construction of LDD and the illuminator enables the user to visualize exactly the surface irradiated by IR radiation. The exposure time and the output of laser power are also controlled and can be displayed on the LED monitor at the front panel. This new device, described here, is compact, low cost, and user friendly.
